Every project seems to trigger the message, even a new, unmodified project: VSCode -> PIO Home -> New Project -> click Build
Also, from the PIO CLI window in VSCode:
$ pio run -h **************************************************************************************************************************************************************************************************************
Obsolete PIO Core v5.1.0 is used (previous was 5.1.1a3)
Please remove multiple PIO Cores from a system:

Also tried a verbose build on a new project, but I’m not sure it illuminated anything new:
$ pio run -v **************************************************************************************************************************************************************************************************************
Obsolete PIO Core v5.1.0 is used (previous was 5.1.1a3)
